摘要： An ordered, 3-dimensional, micro-scale, open-cellular truss structure including interconnected hollow polymer tubes. The hollow micro-truss structure separates two fluid volumes which can be independently pressurized or depressurized to control flow, or materials properties, or both. Applications for this invention include deployable structures, inflatable structures, flow control, and vented padding.

摘要： A system for forming a micro-truss structure including a reservoir having walls and a flat bottom configured to hold a volume of a liquid photomonomer configured to form a photopolymer when exposed to light, a partially transparent mask secured to, or being, the bottom of the reservoir, a release layer on the mask configured to resist adhesion by the photopolymer, and a blocker positioned a first distance below the mask. The system also includes a light source positioned below the blocker configured to produce collimated light suitable for causing conversion of the photomonomer into the photopolymer, and to which the blocker is opaque, and a first mirror, oblique to the blocker, configured to reflect the light from the light source around the blocker and through the mask and into the reservoir. The blocker is positioned to block a straight path of light from the light source to the mask.

摘要： A system for fabricating micro-truss structures. A reservoir holds a volume of a liquid photomonomer configured to polymerize to form a photopolymer when exposed to suitable light such as ultraviolet light. A mask at the bottom of the reservoir includes a plurality of apertures. Light enters the reservoir through each aperture from several directions, forming a plurality of self-guided photopolymer waveguides within the reservoir. The light is supplied by one or more sources of collimated light. A plurality of mirrors may reflect the light from a single source of collimated light to form a plurality of collimated beams, that illuminate the photomonomer in the reservoir, through the mask, from a corresponding plurality of directions, to form a micro-truss structure including a plurality of self-guided waveguide members.
